  Our setting is a Hilbert space of analytic functions in several variables. These functions are usually allowed to be vector-valued. Then we consider a subspace which is invariant under the multiplication by the coordinate functions. Our result is an additive formula of two numerical invariants. The first numerical invariant is the fiber dimension of the invariant subspace, and the second one is the Samuel multiplicity of the associated quotient space.
  I will explain all definitions, and explain the proof of a simple case.
